The Sunnyvale City Council voted June 10 to increase the utility rates for city-provided water, wastewater, solid waste and recycling services.

The spike will include a 5 percent increase in water rates, 9 percent in wastewater, and 6 percent in solid waste and recycling rates.

According to city staff, the average single-family residential monthly bill will be going up by $2.33 for water, $3.04 for wastewater, and $2.41 for solid waste and recycling for a total of $7.78 a month.

The new total average monthly bill will be $128.88, an increase of approximately 6.4 percent over the current year.

“Sunnyvale’s rates for utility services are based entirely on the city’s costs for operating and maintaining its utility facilities and services,” Sunnyvale communications officer Jennifer Garnett said.

“In addition to replacing aging sewer and water infrastructure, some of the increases are necessary to cover rising operational costs such as increases in the price of wholesale water. If the new rates are approved by the council, Sunnyvale’s rates will be at the average for cities in our area.”

The increases will become effective as of July 1.

Each year, staff provides the council with proposed rates and planned changes in rates over 20 years.

Staff reported the proposed increase in water rates was previously planned and covers rising wholesale water costs and large rehabilitation costs for water infrastructure.

The proposed increase in wastewater rates, however, is higher than previously planned. That increase will cover needed infrastructure and capital costs of the city’s aging wastewater treatment plant.

Increases in solid waste rates are also higher than last year’s projected change due to increases in the cost for providing solid waste collection as well as the implementation of the city’s Zero Waste Strategic Plan.

The city has seen increases consistently for the past three years.

In 2013-14, the proposed rate increase for water service was 5 percent, for wastewater service was 6.5 percent and for garbage and recycling services was 4 percent.

In 2012-13, residents saw a 7 percent increase for water, 5.5 percent for wastewater and 4 percent for solid waste services. And in 2011-12 there was an 18 percent increase in water, 5.5 percent for wastewater and 6 percent in solid waste and recycling.
